RE: Scope Woes & Virtual Directories
Can you set the variables that need to be shared in a scope that can be shared? Like the server scope? The only other option would be to handle your sessions manually in my mind. Have a table where you generate unique session keys and assign those to the user via a cookie or url variable. Keep track of last accessed time and that sort of thing. Then you can save whatever variables you want into another table and reference by the session key and variable name. It's more DB intensive but it gives the flexibility you want as long as db datatypes can handle the data you're wanting to shared. You can also let CF manage your sessions, but store the vars you want to share in a table with the session key and variable name so you can query it out from any app. John Burns Certified Advanced ColdFusion MX Developer Wyle Laboratories, Inc. | Web Developer -Original Message- From: jonese [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 24, 2006 2:55 PM To: CF-Talk Subject: Re: Scope Woes & Virtual Directories Howard: Nice idea but the SQL cost is more than we want to deal with.

Re: Scope Woes & Virtual Directories
Create a common app name for all your shared application scope variables. In each site's Application.cfm file, use a CFAPPLICATION tag to get the variables from this scope and put them in the request scope. Then use a second CFAPPLICATION tag to swap the application to the unique one for that site. When you need to write to the common application scope, swap back again with a new CFAPPLICTION tag, etc etc. It will be far quicker that the DB calls.

Re: Scope Woes & Virtual Directories
Another thing I've done when I needed to pass session info into a system that didn't share sessions (CF into PHP, or Perl into CF) is to create a script on either side that receives the variable data as URL parameters, then creates the session accordingly. You direct every site-to-site link through this script. One parameter is the eventual final URL and all the others are variables to stuff into the new session. The downside here is that URL parameters are inherently insecure.

RE: Scope Woes & Virtual Directories
You don't need unique application names. Lets say you have one site and at the top of it you have then you set some application variables somewhere in there. Then, you have another site on the same server, you can put in that site and it will have access to the variables that are set in the first site. However, keep in mind, you want to be careful about multiple sites setting and getting variables to make sure that you're not relying on a variable that may not have been set. Especially when the server is rebooted or something like that. Many people have the misconception that the tag has to go in the Application.cfm but that's not true. It can go at the top of each individual page and you could leave out the Application.cfm altogether. The Application.cfm just makes it easier because it gets called everytime.

I dimly remember some Java trickery you can do (in MX of course) to grab
variables from the server for a given application. However, that path is
likely fraught with peril.
My first inclination would be to create a central repository for shared
variable values. Much like the way CF can save client scopes to a database.
Create a database table that stores the session, using some user value that
is unique across applications as the primary key (could be session, I can't
remember if they are unique to the server or to an app). Create a custom tag
that reads and writes an arbitrarily named struct ("sharedVariables" for
instance) to this table. Put this custom tag in Application.cfm and
OnRequestEnd.cfm so the shared variables struct is refreshed and saved for
each request. When you need to read or write a variable that should be
shared, you use the "sharedVariables" struct as the scope.
Pros: no additional work when you add a 51st application.
Cons: read and write to the database for each user request, requires a user
unique key.

RE: Scope Woes & Virtual Directories
It depends on the scope you're using. If you're talking application and session variables, you need to define that these pages are part of the application, thus allowing it to access the scoped variables.
